10.) Priority Queue (basic)

 write a programe to remove all element from a priority queue except smallest one.

import java.util.PriorityQueue;

public class RemovePriorityQueueElements {

   public static void main(String[] args) {

     

      // Creating a priority queue

      PriorityQueue<Integer> pq = new PriorityQueue<>();

     

      // Adding elements to the priority queue

      pq.add(10);

      pq.add(20);

      pq.add(15);

      pq.add(30);

      pq.add(25);

     

      // Printing the original priority queue

      System.out.println("Original Priority Queue: " + pq);

     

      // Removing all elements except the smallest one

      while (pq.size() > 1) {

         pq.remove();

      }

     

      // Printing the priority queue after removing elements

      System.out.println("Priority Queue after removing all elements except smallest one: " + pq);

   }

}
